The clinical distinction between neurology and psychiatry is increasingly appreciated as awkward and artificial. Neurology has traditionally focused on organic disorders with identifiable pathology, whereas psychiatry has focused on functional disorders without observable pathology.

     The following was written by Mark Ralph Rowe on January 13, 2016 at 5PM Pacific Time in the city of San Diego, California: "functional disorders have no observable scientific pathology, hence functional disorders have unidentifiable pathology therefore the patho-physiological basis has not yet been discovered for functional disorders that has been the focus of psychiatry for the last 226 years. Neurological disorders do have pathology that is scientifically observable and identifiable."
